Simply said LED display control card is divided into: single color control card, colorful control card, full color control card.


LED display control card used:

1. Regardless of what color LED display, different brands of control cards from hardware to software are different. The same brand is also divided into different models, the function is very different.

2. Control cards are equipped with software. Monochrome screen small area of the general use of a simple non-partition control card, cost-effective, slightly larger area can be used partition control card, will be more expensive.

3. Control card and computer connection methods are: network port (TCP / IP), serial (RS232, RS485), U disk conduction, GPRS wireless connection, Zigbee wireless connection and other major ways.


LED display control card selection method:

First of all, to understand their own to do the LED display specifications, size, calculate the points, ask the customer needs the effect is synchronous, or asynchronous, need no secondary development;


Then, determine the synchronization asynchrony, determine the effect, determine the range of points to determine the price range, and finally determine the card; card is not expensive, the key is applicable, available, easy to use. It is best to understand the software according to their own to select the card, each LED display manufacturers with the range are almost the key is the software is not suitable for their own and customers.


LED display control card can not find how to do:

1. Make sure your control card is with the software.

2. Check whether the cable is off, loosen, check and confirm the serial cable used to connect the control card with the control card to accompany, and some control card with straight (2-2,3-3,5-5) some control Card with (2-3,3-2,5-5).

3. Ensure that the control system hardware is properly powered on. (+ 5V)

4. Control the LED display control software and the control card of your choice to select the correct product model, the correct transmission mode, the correct serial number, the correct baud rate and control software provided within the DIP switch diagram to set the correct control The address bits and baud rates on the system hardware.

5. If after the above checks and corrections still do not load, please use a multimeter to measure whether the connected computer or control system hardware serial port is damaged. To confirm whether it should be returned to the computer manufacturers or control system hardware back to testing.
